Who says you need to log in to the ECU you can log it into something like a SD card or something simple....Then use the F-T software to interpret the log file and then generate the new maps and ECU image....then you can flash it....It would only need to log gear, TPS, RPM, and the wide band O2 sensor.....Doesn't sound too complicated...

Check out the ZT-2 and the Blackbox logger. I use it as described above.

If you wired PCV as per PCV manual you will see the % of the baffles actually opening not the twist of the throttle control handle.

To calibrate PCV for Flashtune - use diagnostic mode d01. Calibrate according to d01 that with engine not running and ignition on.

When the bike is running you will be at about 2% throttle on PCV. This is what you need if you plan to apply the throttle maps via flashtune later.

If you calibrate pcv 0% to the point when the bike is running, then this will provide inconsistency on low throttle openings when you apply the pcv map via flashtune.

Hi Elwin,
I wonder about PCV+AT calibration and do not understand something I would be very grateful for help. For example If we setup in PCV soft. 0.7V as min Voltage(engine idle) and 4.2V for WOT do we need still check d01 ? What for we need calibrate throttle position in do1 mode (diagnostic/TPS)? does it mean that when PCV is wired to ECU it can changes std. TPS reading for ECU throttling position and for this we using calibration mode do1?

I need calification

1. I understand that whatever PCV is connected or not, the throttle position in diag code should be 15 for (ignition on and idling engine) and it is 0% indication of throttle position and 0.7V in PCV soft. .
BUT base on your prev. comments and how I understood it the throttle opening % indication on idling should be visible as 2% in PCV sof. yes?

2. About diagmode. It is not possible to open the throttle on 100% in d01 diag mode because of Throtle by Wirre system and max what we can achieved is 20% code 57 ( i need calcification). It means for me that we can't calibrate throttle position in diag. mode using hand/throttle or I'm wrong.

Cutting fuel is not good for r1 engine. backfires are not a problem for r1 engine - it is by design.

1. Ignition is set to 60-78 in engine breaking to help the engine breaking.
2. Spraying fuel in cylinders helps to cool them.

Did you read what I said that I think it kills both. I also know that when it activates it kills fuel because the instantaneous fuel mileage goes to 99.9 because the injectors do not cycle. I also know that if you hook up a QS sensor to a PCV, all you do is kill fuel and it works with no problem. So I really don't think the 40-80 ms with no fuel will really hurt anything what so ever it may only like 2 firing cycles per cylinder at 10kRPM ....I have not gotten an official answer yet to the question.

You could edit the YCC-T Table an put a 100% in the top right box (800rpm and 100%APS) so that when the engine is off it is at you can still get 100%. I would use that map only for diagnostics though...even through you cant actually ever get there....just for safety....

But Tad still need clarification what we doing this calibration in the diag. mode for? if in the PCV soft. we can set-up voltage for WOT, really I'm confusing .

In PCV/AT doc. about throttle by wire system is clearly stated that only what we should do is just press reset button when ignition is on.

And now is the most important question and is directly related to prev. Elwin post. On the engine idling in PCV+AT soft. should be visible 0% or 2% of throttle position (As far as I understood Elwin said that should be 2% for FT fuel map match).

Apart of this the DYno Jet. documentation is really terrible and not professional in many ways similar as their products(obsolete and with many problems after so many years of production)

Strange. The Bazzaz system is cutting ignition, when using the QS function.
One of my teammates have the YEC race system from Yamaha, and it's also cutting ignition. The fuelcoils is not used to QS, and is operating normal during the shift. Thats why it backfires sometimes, when the timing hits the tre cylinder ignition, because there is then more fuel to be burned, than on the rotation with only one cylinder firing.

, I don't have a PCV so I am not sure what it really requires. SySt seems to have good install PCV info.

The PCV does not control the coils unless the add-on ignition module is installed. But with just the standard PCV with a QS sensor hooked up it will just kill fuel for QS....

D01 allows to open throttle to 100% not problem, just wist the throttle and you will see it.

15 - 16 in the d01 mode readout on the dash is ok setting for the fully closed throttle position.

Not sure how more clear and simple that all can be:

1. Go to diag mode d01.
2. Check if dash reads 15-16 if not adjust your TPS mechanically.
3. While in d01 go to PCV calibration
4. While in d01 set zero to the current voltage
5. While in d01 twist the throttle to the max, hold it there and set PCV 100% to current voltage.
6. Ignition off to get out of Diag. mode. Ignition on and start the bike.
7. Heat bike up.
8. Check the PCV TPS reading on the PCV fuel table. You should see PCV working in 2% map with table tracer enabled while the bike is idling.

PCV in this case indicates more than 0 because when the bike idling ECU controls the baffles for the idling so it is not zero. Even if you stop the engine it will not put the baffles to zero, expecting the startup. When you apply PCV map via flash tune, the zero tps on PCV is treated as zero tps on fueling map which will be correct only if you follow procedure above.

Above procedure is valid only for PCV map you building for flash tune specifically. If you planning on riding with PCV connected all the time without applying changes to flashtune it would be better to set zero as per PCV manual.

Also remember that you cannot use the map build on standard pcv calibration to flash with flashtune as you get bad results on low TPS (unless flastune corrects current PCV map import logic) Also when you apply Standard PCV maps via flash tune - it will be a problem too.

Again the problems are noticeable only on low trottle openings like 2%, 5%.

Yes, but where would it store the log? And how would you access the log? The only way the FT software writes to flash ROM is by first wiping the ROM memory and then writing. Obviously that sort of operation would not work for storing log data. It would be nice if two input/output pins on the ECU could be used for serial communication and then have an external device simply log ECU information sent through the serial lines. Of course, doing it this way you might as well use an external data logger in the first place. I built a suitable logger out of an Arduino board and an SD card shield. I am currently logging TPS, RPM, Speed sensor, MAP, AIT and AFR at 20Hz but it's capable of logging at over 50Hz. Total cost was under $100. Of course, I am also using an already existing wideband setup (Innovate Motorsports LC-1). I also made a program for my computer that will load up a map file and log file and generate a trimmed fuel map based on a target AFR map. So I guess I really don't need FT to make an AT feature anyhow .

Hi SYSt I have big appeal could you explain in a few bulletpoints (step by step) how the PCV+AT unit should be calibrated for FT (rn22)?

What Elwin posted 3 posts ago explains the procedure very well. Have you read it yet? I will add though that the PCV must be energized when you twist the throttle in diag mode or else the throttle will only partially open and will sort of "freeze" due to what must be a signal error. On an 07-08 and possibly beyond: To energize the PCV the injector/fuel pump circuit must also be energized (it's the circuit the PCV gets it's power from). You can do this by disconnecting the fuel pump connector and apply 12v+ to the proper terminal in the connector on the harness side. Consult the service manual for the right terminal. I'm not sure if the 09+ wiring is the same as the 07-08 in that regard but the idea is the same, the PCV must be energized and connecting it to a computer via USB does not cut it (Major ground offset between computer and TPS).

If there is something you are still confused about, ask a specific question so we know how to help.

Auto tuning is not as easy as just having it on all the time and riding the bike. You actually need to do the runs as on the dyno.
The button to enable-disable autotune is mandatory.
You must have the latest update to PCV software for the autotune to work correctly.
Correct way to auto-tune:
0. Always tune well heated engine - not just coolant temperature but the engine block (oil) must be heated up to at least 80C.
1. Have auto-tune off in normal conditions
2. When you ready to do a tune run, flip the button to enable autotune and twist throttle to "required"% gradually over vise ECU will do "accelerator pump" enriching mixture momentarily (yes it does that). So start with 1500 - 2000 pm with a goal to get to required tps position when you hit 3000 on high throttle openings and less on the lower openings. When you hit rev limiter, flip button again to disable auto tune so it would not f@ck up the map during engine breaking/neutral throttle.
3. You need about 10 runs to be sure PCV got it right.
4. Repeat point 2 for 100%, 80%, 60%, 40, 20, 15, 5, 2. You will not hit rev limiter on lower throttle openings, so flip the button when RPM stabilize.
5. You need to have linear proportional YCC-T map to do precise tuning. You can change it to anything you like later.
6. You need to have something indicating your tps while you autotuning - for example power commander LCD unit. You can also use same unit to datalog to SD card and then re-calculate fueling corrections based on that log.
7. When you done - accept changes to PCV fuel table.
8. Repeat the same process at least 5 times.
9. Now flash PCV map to ECU.
10. Repeat all above another 5 times at least. Watch out for errors in mapping. Your experience will grow so eventually you will get it right.
I would recommend to auto-tune on gear 4, so you have reasonable load, and time for AT to sample.
